Report tables refresh data

#1

Hi, I’m working on an interface based on an iThink (Stella) model for my major degree. It’s a turn based interface. I’m having a problem with the numbers that the reports table shows. On the first image you can see the initial conditions of the model on the “Granjas>Edad y cantidades” page. I run one step of the model and the graphs refresh (See Pic 2) but the data on the table is the same.

Thanks for the help

Hi Andres,

We were able to see the issue when selecting
menu: Granjas | Edad y cantidades de pollo
and it displayed the same data for every column results.

We are currently investigating.

When you run your Stella model independently (standalone), does the Stella model for the cities (Casa Vieja, San Fernando, Siberia, etc.) have different results? We are wondering if it could be a Stella model issue?

Hi,

The reason you are seeing differences between the graph and the table has to do with how STELLA handles the data over time.

When STELLA runs, not all variables are calculated in the most recent time period. For example, if youre model has time running 1 to 10, and you are at time 3, then

  • “Time” has values for times 1,2,3
  • all stocks have values for times 1,2,3
  • all other variables (e.g. converters) have values for times 1,2

This is because the converters are calculated and reported at the end of the time period, just before the step, so they can include the values of the stocks and the latest inputs.

You can see this in your STELLA model if you run the model with a pause interval of 1. Make a table with different variables. You will see Time and all stocks with values for the most recent row. But all converters will be one row behind.

What you are seeing in your Forio simulation is no values being shown for the last time period (the Time is 2 in the pictures you provide).

In your example, you are showing stocks in the graph, and converters in the report. Hence the report has the column with blank time.

We’re still thinking about how to show this in a meaningful way. One thought is to hide any columns where all the values are blank. We would do this in an upcoming release.

Let us know if you have any other difficulties.

Regards, WILL

P.S. Thank you very much for posting the URL of your simulation and the screenshots. Made it much easier to investigate.
